US 9,286,382 B2 · Method and system for simultaneous playback of audio tracks from a plurality of digital devices

Abstract

A method for simultaneous playback of audio tracks from digital transceiver devices, which are adapted to define a communication network. The digital devices store audio tracks to be played. One of the digital devices is actuated as a Master device (M) and the remaining N digital devices as Slave devices. The master device generates a pilot signal by selecting a pilot audio track to be played from among stored audio tracks and by adding a synchronization frequency (fS) to the pilot audio track, having an assigned value that falls out of the sound wave frequency range. The Slave devices receive a pilot portion of the pilot signal and extract the synchronization frequency and the received part of the pilot audio track. The slave devices use the pilot to identify a stored track to be played using the synchronization frequency as a sampling frequency.

Dependent claims

A method, comprising:

generating, using a master device of a communication network, a pilot signal including at least a portion of an audio track and a synchronization signal;
transmitting the generated pilot signal;
receiving, by at least one other device of the communication network, the transmitted pilot signal;
retrieving, by the at least one other device and based on the pilot signal, a stored copy of the audio track;
and
synchronizing playback of the audio track by the master device with playback of the retrieved copy of the audio track by the at least one other device based on the synchronization signal included in the received pilot signal.
